摘　　要：根据全响应连续相位调制信号在不同调制指数下的基带循环谱,由数字调制信号的基带循环谱与带通循环谱的关系式,推导了其相应带通信号循环谱的表达式并进行了详细的分析,得出了不同调制指数下循环频率与载频、峰值频偏以及码元宽度之间的关系式.仿真实验证明这些结论是正确的.The general cyclic spectral representations of the full response continuous phase modulation （FR-CPM） are developed and analyzed in detail based on the analytic expression of the corresponding base-band cyclic spectra. The relation of the cyclic frequency with the carrier frequency, symbol period, and peak frequency deviation is obtained within the different modulation indexes. These conclusions are proved by the computer simulations.

关 键 词：全响应连续相位调制 循环平稳 循环谱
